BMW E9x & E8x CBS Oil Change Value Adjustments DIY (coding)


Foreword

1. This is a summary made in part from a DIY found on Bimmerpost, I am not the mastermind behind this
2. This DIY compresses scattered information into one central DIY and adds some of my own insights
3. Read this entire DIY before starting.
4. By following this DIY, you are doing so at your own risk, I am not responsible for any damage that may occur to your vehicle.
5. Warning: This process may trigger a tamper value for the CBS that could cause a headache if still under warranty: "Also, executing 'cbs_reset' Job you set MANIP_CBS flag, which essentially says: "System has been tampered with".." --> http://www.bimmerfest.com/forums/sho...p;postcount=19
6. This process will reset the CBS value, so if you did an oil change a few months back, you'll need to remember when to change the oil next without relying on the CBS reminder.
7. Before beginning, attach a battery charger or tender to the car to keep the battery powered up. Turning the headlights to off is also a good idea to preserve the battery. You do not want the battery dying while in the middle of coding. I'm not sure what would happen, but I presume damage to the code within the module, in this case the DME.
8. After each Oil Change + OCI reset, you'll need to perform this coding. You're manually adjusting the CBS data for the current oil life by saying it is x percent of 100


Requirements

You will need INPA, and Tool 32 to accomplish this, both are contained within BWM Tools 2.12. You will also need a K+DCAN cable to connect your BMW.
If you are new to coding, begin here before progressing further: http://www.e90post.com/forums/showthread.php?t=451145


Procedure

Step 1: Disable JB4 if equipped (Map 0), or any other tuning which may interfere.
Step 2: Connect car, confirm connection with INPA, close INPA
Step 3: Open Tool 32, run MSD80.prg, or other DME file if applicable
Use Real OEM to confirm your vehicles DME --> Enter the last 7 of your VIN --> Engine Electrical Systems --> DME

DDE6: Diesel (03/2005 - 09/2007)
DDE7: Diesel (09/2007 - 2013)
MV946: 116i, 118i, 120i, 316i, 318i, 320i, 320si
MSV70: 125i, 130i, 325i, 330i
MSV80: 128i, 328i
MSD80: 135i, 335i (N54), 325i (N53) (06/2006 - 07/2008)
MSD81: 135i, 335i, 1M (N54), 325i (N53) (03/2008 - 03/2013)
MEVD172: 135i, 335i (N55)
MEVD1726: 135i, 335i (N55)
MSS60: M3

Step 4: Navigate to cbs_daten_lesen and run the job
Step 5: In the results, find COU_RSTG_CBS_MESS_WERT make a note of the value here, it will be between 0 and 30. This value will be needed later on if you decide to adjust the month/year manually. The below screen capture is of my car, notice how the value here is 08. This value is the number of times the CBS oil counter has been reset, so my car has had the CBS oil counter reset 8 times, or has had 8 oil changes done in its life time (assuming the CBS reset was done correctly each time the oil was changed)



Step 6: Close the results and navigate to cbs_reset. In the Arguments box, enter oel;XX;YY, where:

XX = the service interval (Approximate percentage of the original value, in multiples of 1. The 100% value is 27,580km)
YY = your current CBS counter value

A few options for XX, in increments of 5, are:
oel;50;YY=14,000km (13790km rounds to 9,000 miles)
oel;45;YY=12,000km (12411km rounds to 8,000 miles)
oel;40;YY=11,000km (11032km rounds to 7,000 miles)
oel;35;YY=10,000km (9653km rounds to 6,000 miles)
oel;30;YY=8,000km (8270km rounds to 5,000 miles)
oel;25;YY=7,000km (6890km rounds to 4,300 miles)
oel;20;YY=6,000km (5510km rounds to 3,700 miles)
oel;15;YY=4,100km (4130km rounds to 2,500 miles)
oel;10;YY=2,700km (2750km rounds to 1,700 miles)

To pull this all together, my counter value is 08 and I want an oil change interval of 8,000km, so I entered: oel;30;08

Once you have entered the value, double click on cbs_reset to run the job, or press F5.




Step 7: Navigate to cbs_daten_lesen and run the job again, view the info and look for a change in RMMI_CBS_WERT value. This value is multiplied by 10 to give the OCI, ie 827 x 10km = 8270km for the OCI.




Step 8: Check the Service Info section via the stalk to see your Oil Change Interval
Step 9: Enable JB4 if equipped, or any other tuning disabled in Step 1



Happy coding!

Nice work! Glad to see some coding make it into this forum. I wonder if it's possible to change the brake fluid interval for those of us running race spec stuff.

Thanks 1AA!!

I'd imagine it's basically the same procedure, just gotta figure out the code locations and time scales for brake fluid vs oil vs other maintminder stuff.

+1

You would just need to discover the argument needed to adjust it, I've read posts that alluded to users coding it but have yet to find that info.

Also original post updated with additional values for distance

Upon revisiting some older coding posts and looking again at the CBS reset prompts, running them through a translator... (See image below step 6, yellowish box). Prompts 1 through 3 are used in the above DIY, 4-10 are not, which retains the other information as was previously programmed.

Prompts 4 and 5 would allow you to customize the month/year of the oil service by adding these values (ie oel;XX;YY;MT;YR)

1: CBS_Kennung: CBS ID
2: CBS_verfuegbarkeit: CBS Availability
3: CBS_anzahl_service: CBS Number Service
4: CBS_ziel_monat: CBS Target Month
5: CBS_ziel_Jahr: CBS Target Year
6: RMM_CBS_Wert: RMM_CBS_Value (Not sure what RMM is)
7: ST_UN_CBS_RSTG: (not sure what these are abbreviating? Dackelone maybe you can help shed some light)
8: FRC_INTM_Way_CBS_Mess: FRC INTM WAY CBS Measuring (again, not sure whats being abbreviated)
9: FRC_INTM_T_CBS_Mess: FRC INTM T CBS Measuring (Same comment as 8)
10: Res_Byte: Reset Byte?

The trick for CBS brake fluid service would be determining the ID that the CBS uses for brake fluid, then using either a 3 prompt or 5 prompt string you could be able to reset it.

At the moment the following prompts I know to be confirmed for prompt 1 above, I'm making some assumptions on what the abbreviations translate to in German, having only a single letter to go off of:
OEL = Motor Oil (Motoroel)
BR_V = Brake Pad Sensors - Front (Bremse Vorderseite)
BR_H = Brake Pad Sensors - Rear (Bremse Hinten)

I have no idea when it comes to line coding. But I asked some friends about this. I'll get back to you.

Ok, did more digging... When you click 'CBS_Reset' once, Tool32 actually gives you all the possible variations you may use. The raw export is pasted below from my car, I would imagine Brfl is brake fluid/Bremsflüssigkeit in German. I've run it through a translator below.

Ok 1AddictsAnonymous I talked to my BMW AG "source"... he gave me these screen shots. Maybe this will make sense to you. Like I said I am not a "coder". He uses: tool32...

ST_UN_CBS_RSTG...

[6MT_Addict]

Thanks Dack. This mirrors the info I was able to pull from Tool32 as well. I tried altering values progressively, ie prompt 1-3, prompt 1-4, etc. Looks like only 1-3 are actually editable via Tool32 for oil.

[v3n0m]

Has anyone been able to get this to work on an f-series? I can read the data but when I try to run cbs_reset, it gives me the error:
ERROR_ECU_CONDITIONS_NOT_CORRECT

At first I thought it might have to do with the ignition being in aux or on, but I tried both and it didn't work.

Perhaps you should post this question on the e90forum coding section - there are more "experts" over there. or maybe bmwretrofit might know more ?

The DME file may not be correct, but that's just a guess. I haven't experienced that error myself. Dack has a good suggestion, the coding forums will have a larger knowledge base

[AutoEngBM95]

For some reason, when I try to open my MSD80.prg file in Tool 32, it doesn't load, it just gets stuck on a blank window within Tool 32 labeled Results.

You don't have to revert to using those Jiffy Lube windshield stickers. I guess you haven't seen this thread of mine. I made it a sticky so it's easy to find...

DIY resetting service "due" lights…

All you need is to enter the hidden menu on the speedo cluster and then use the BC and RESET buttons to reset your service(oil) lights.

Of Course I've seen your sticky Dack, but I'm only coming back to the forums since I've been away a few years and wanted to give everyone who looked at this thread a little chuckle.

But also, I'm switching to oil changes every 5k miles now, so... Either follow this monstrosity and trick the computer via INPA, or give myself a little old school reminder right there on the windshield.

I got a chuckle out of that!

I have a full maintenance log for all my vehicles, which is super useful for this. I gave mileage service performed at and next due.

Whatever you use for in vehicle reminder I find keeping some form of log extremely valuable
